This release resolves several issues affecting campaign scheduling and compatibility.
A critical scheduling bug introduced in version 2.8.17 could prevent campaigns from running automatically on sites using the Use Alternate WP Cron or Disable WPeMatico schedulings options. Scheduled campaigns could appear active but would only run when triggered manually. This issue has now been fully resolved.
Additionally, this release fixes a PHP notice related to cron schedule registration during plugin loading and resolves a PHP 8.1+ deprecation warning that could appear when admin notifications were displayed for the first time.
These fixes improve overall stability and compatibility across modern WordPress and PHP environments.
